      <p>PNG format.</p>
<p>A loss-less compression format for images. This format is well suited for
images with hard edges, such as screenshots or sprites, and images with
text. Transparency is supported. The PNG format supports images up to
2,147,483,647 pixels in either dimension, though in practice available
memory provides a more immediate limitation on maximum image size.</p>
<p>PNG images normally use the <code>.png</code> file extension and the <code>image/png</code> MIME
type.</p>
